Printing system and control method thereof

Abstract

In a printing system which feeds a sheet from a plurality of sheet storage units and prints an image on the fed sheet, and a control method thereof, when a sheet storage unit selected as a paper feed source does not store sheets of a size designated by a print job, and a sheet storage unit which stores sheets of the size designated by the print job does not exist in a group to which the selected sheet storage unit belongs, the user is notified of a sheet storage unit in the group as a sheet storage unit which should store sheets.

What is claimed is: 
     
         1 . A printing system which feeds a sheet from a plurality of sheet storage units and prints an image on the fed sheet, comprising:
 a storage unit configured to store a size of a sheet set in each sheet storage unit of the plurality of sheet storage units;   a registration unit configured to register, as one group, at least two sheet storage units out of the plurality of sheet storage units;   a first print control unit configured to, in a case where a sheet storage unit selected as a paper feed source stores a sheet of a size designated by a print job, print an image on a sheet fed from the sheet storage unit;   a second print control unit configured to, in a case where the sheet storage unit selected as the paper feed source does not store a sheet of the size designated by the print job, feed a sheet from a sheet storage unit which stores a sheet of the size designated by the print job within a group to which the selected sheet storage unit belongs, and print an image on the fed sheet; and   a notification unit configured to, in a case where the sheet storage unit selected as the paper feed source does not store a sheet of the size designated by the print job, and a sheet storage unit which stores a sheet of the size does not exist in the group to which the selected sheet storage unit belongs, notify a user of a sheet storage unit in the group as a sheet storage unit in which a sheet is to be set.   
     
     
         2 . The system according to  claim 1 , further comprising a paper replacement condition setting unit configured to designate, for each of the plurality of sheet storage units, whether sheet replacement is possible,
 wherein said notification unit notifies the user of the sheet storage unit for which sheet replacement is set to be possible.   
     
     
         3 . The system according to  claim 1 , further comprising a paper feed history storage unit configured to store a paper feed history of each of the plurality of sheet storage units,
 wherein said notification unit notifies a sheet storage unit having a low paper feed frequency preferentially as the sheet storage unit in which a sheet is to be set.   
     
     
         4 . The system according to  claim 1 , further comprising a paper replacement condition setting unit configured to designate, for each of the plurality of sheet storage units, whether sheet replacement is possible,
 wherein in a case where said notification unit notifies a sheet storage unit for which sheet replacement is set to be impossible as the sheet storage unit in which a sheet is to be set, said notification unit notifies the user of a message which prompts the user to return, after an end of the print job, a sheet of the sheet-replaced sheet storage unit to an original sheet.   
     
     
         5 . A control method of controlling a printing system which feeds a sheet from a plurality of sheet storage units and prints an image on the fed sheet, comprising:
 a storage step of storing, in a storage unit, a size of a sheet set in each sheet storage unit of the plurality of sheet storage units;   a registration step of registering, as one group, at least two sheet storage units out of the plurality of sheet storage units;   a first print control step of, in a case where a sheet storage unit selected as a paper feed source stores a sheet of a size designated by a print job, printing an image on a sheet fed from the sheet storage unit;   a second print control step of, in a case where the sheet storage unit selected as the paper feed source does not store a sheet of the size designated by the print job, printing an image on a sheet fed from a sheet storage unit which stores a sheet of the size designated by the print job within a group to which the selected sheet storage unit belongs; and   a notification step of, in a case where the sheet storage unit selected as the paper feed source does not store a sheet of the size designated by the print job, and a sheet storage unit which stores a sheet of the size does not exist in the group to which the selected sheet storage unit belongs, notifying a user of a sheet storage unit in the group as a sheet storage unit which is to store a sheet.
